LOCKING DEVICE FOR BED-BOTTOMS.

SPECIFICATION forming part of Letters Patent No. 372,369, dated November 1, 1887.

Application filed August 1, 1887. Serial No. 245,859. (No model.)

To CLZZ whom it may concern:

Be it known that I, OSCAR S. Fosrnn, of Utica, in the county ofOneida and State ofNew York, have invented certain new and useful Improvements in Locking Devices for Bed- Bottoms; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in devices for locking the sections of bed-bottoms in open adjustment, and also to provide suit able means for preventing the slipping of the springs ofsaid bed when the sections are folded; and it consists in certain features of construction and combinations of parts, as will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan View ofa bed-bottom held in open adjustment by my improvement. Fig. 2 is a view in elevation of the bed-bottom folded. Fig. 3 is a detached view of the hinge-section, showing the manner of attaching the chains which prevent the displacement of the springs. Figs. 4 and 5 are detached views of the locking devices and coupliughiuge.

A represents one section of a metallic folding bed-bott0m, rectangular in shape, and composed of slats a a a a, secured at their ends to the cross-slats a, and provided with cross slats or strips 1) b, which latter are secured to the cross-strips at points between the cross slats a.

, Stout binding-wires B are secured in loops formed in the upper coils of the outer springs of each section of the bed-bottom and the adjaccnt ends of the hinge-couplings B, which latter are located in a plane passing between the two sections of the bed-bottom.

The hingecoupliugs are provided with outwardly-extending wings or flanges c, secured thereto or preferably cast integral therewith, and provided with holes or perforations c for the attachment of chains or wires. These chains or wires, are secured to the adjacent springs, and prevent the springs,when the bed is folded, from moving out of their proper po sition.

D represents the locking device for locking the sections of the metallic bed in open adj ustment, and it consists of a narrow strip of metal, E, having a U-shaped termination, e, at one end, made by bending a small portion of the strip back on itself, and provided with a perforation, e, in its other end to allow of its attachment with the slat a of the one section of the bed-bottom.

Secured in swinging adjustment to the bar E near its ends are the keepers F, each of which consists of a strip of spring metal having one end,f, bent at right angles to itself for the purpose of closing the U shaped bend and locking the section which it engages securely against folding.

\Vhen it is desired to lock the sections of the folding bed-bottom together in open adjustment, the bars E are swung around and the two sections brought close enough together to allow the bar a to pass over the U-shapcd ends of the bars E, and then separated or moved apart until the slat enters the U shaped bend of the bars E. The keepers F are then swung around until they come in the same plane with the bars E,whereit is released, whcn,on account of its springing qualities, it will remain in that position and serve as an additional means for locking the sections in open adjustment.

Having fully described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. In a folding bed, the combination, with the two sections, each consisting of a series of springs, and binding-wires passing through loops formed in the upper coils of the outer row of springs,and hinges connecting the meet ing ends of the bindingwires, o'fch ains or other flexible devices connecting the end springs on the meeting edges of the section with the hinges connecting the binding-wires, substantially as set forth.

2. In a folding bed, the combination, with the two sections hinged together, of locking devices for locking the sections in open adjustment, each locking dcvice consisting of a bar pivoted at one end to one section of the bottom and hook-shaped at its opposite end to engage a slat of the other section, and a keeper pivoted to the bar and adapted to confine the slat within the hook-shaped end, substantially as set forth.

3. In a folding bed-bottom, the combination, with the two sections, each consisting of slats, springs seated on the slats, and a binding-wire passing through loops formed in the upper coils of the outer row of springs, hinges connecting the meeting ends of the binding-wires of the two sections, and chains or other flexible devices connecting the hinges with the end springs on the meeting edges of the two sections, of locking devices for locking the two sections of the bottom in open adjustment, each locking device consisting, essentially, of a bar or strip pivoted at one end to the inner slat of one section and hook-shaped at its opposite end toengage the adjacent slat of the I5 OSCAR s.
